JOSEPH N. MONEAL, OF BROOKVVAY, MINNESOTA.

GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 692,330, dateclFebruary4, 1902.

7 Application filed November 2, 1901. Serial No.80.905- (N0 model.)

To aZZ whom it may concern:

Be it known that I, JOSEPH N. MCNEAL, a citizen of the United States,residing at Brockway, in the county of Stearns and State of Minnesota,have invented certain new and useful Improvements in Governors, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

My invention relates to speed-governors to regulate the motion of lightmachinery, and is especially well adapted for use in connection withgeared wind-mills.

The object of this invention is to provide a device of this class, ofsimple and inexpensive construction and automatic in its oper ation,which will transmit a steady motion to the driven shaft or mechanismused. I attain this object by the construction illustrated in theaccompanying drawings, in which Figure 1 represents a perspective viewof the invention. Fig. 2 is a detail view showing the adjustablebelt-tightener of the device.

In said drawings, A represents the drivingshaft, which may be thevertical shaft of a wind-wheel, having vanes of suitable form. Saidshaft carries a bevel gear-wheel a, secured thereon to give motion toany desired mechanism. At right angles to the shaft A there is placed ashaft B, carrying on one end a bevel-gear b, which meshes with the geara. Said shaft B is carried in bearings c, mounted upon a rectangularhorizontal frame 0, which may be secured to the frame carrying thewind-wheel or to any other stationary support.

Upon the end of the shaft B opposite that occupied by the gears b ismounted a ballgovernor D of ordinary construction, having its outer bosscl secured to the shaft B. Said boss has two arms e pivoted thereto, andballs 6 are adjustably secured to said arms. To the arms e are pivoted,a short distance from the balls, arms j, which have their inner endspivoted to a sleeve F. The latter, adapted to slide upon the shaft B,has a groove in its periphery to receive loosely therein one end of arod G, which end encircles said groove.

Mounted upon the frame (J there is also a shaft H, parallel with theshaft B, which carries upon one end a pulley h, from which a steadymotion can be transmitted to any suitable mechanism bya belt (not shown)adapted to be mounted upon said pulley. To transmit an adjustable motionfrom the shaftB to the shaft H, the shaft B carries a cone-pulley B andthe shaft H a cone-pulley H but their large ends are located adjacent toopposite sides of the frame 0, and they are connected by an endless beltI, mounted thereon. To automatically shift the position of the belt Iupon the cones, the rod G, controlled by the ball-governor, is used. Forthis purpose said rod is made to pass between the cone-pulleys andthrough the loop of the belt,being retained at a suitable height by theguide-eyes k, inserted in the top of the frame 0. The rod Ghas mountedthereon two friction-rollers g to bear against the edges of the beltWhile shifting it. When the shaft B revolves faster than is desired, thetoo-rapid centrifugal motion of the balls 6 of the governor pulls thesleeve F away from the small end of the cone-pulley B and the rod Gpulls the belt I toward said small end, and consequently the large endof the cone-pulley H and reduces its speed.

To counteract the action of the governor D and its sleeve F upon the rodG, there is socured thereto adjacent to one of the frictionrollers g oneend of a chain or cord m, which is made to pass over a guide-pulley n,mounted upon the frame 0, the opposite end of the cord hanging down, andcarries adjustable weights M upon said end of the cord.

To keep the belt I under constant tension, an adjustable belt-tighteneris used, which consists of a roller N, fully as long as thecone-pulleys. The ends of said roller are pivoted in arms 79, which haveone end pivoted to brackets q, pendent .from the under side of the frame0, so that the roller N bears normally upon the inner surface of thebelt I. To render the pressure adjustable, weights r are adjustablymounted upon the arms P, as shown.

Having now fully described my invention, I claim- 1. In aspeed-regulator, the combination of a vertical shaft, carrying abevel-gear, a horizontal shaft carrying a bevel-gear on one end, aball-governor and its sliding sleeve on the opposite end of said shaft,a rectangular frame carrying said shaft, a cone-pulley upon said shaft,a second shaft having a belt-pulley on one end and carrying acone-pulley, a belt uniting said cone-pulleys, a rod passing through theloop of said belt and having one end connected with the sleeve of theball-governor, friction-rollers upon said rod, and a weighted cord alsoconnected with said rod, substantially as described.

2. In a speed-regulator the combination of two parallel shafts,cone-pulleys upon said shafts, a belt uniting said cone-pulleys,aballgovernor having its sliding sleeve mounted upon one of said shafts,a sliding rod having one end connected with said sleeve and passingthrough the loop of the belt, two frictionrollers upon said rod, arectangular frame carrying the cone-shafts, guide-eyes mounted upon saidframe to guide the sliding rod and JOSEPH N. MCNEAL.
